MIP stands for multum in parvo meaning "much in little". Mipmaps are smaller precalculated versions of the original texture. The edge length of the next smaller mipmap level is half of the previous image.

Each Mipmap level (LOD - level of detail) represents what the texture
would look like at a specific distance. The main purpose of mipmapping
is to reduce moiré patterns in minified textures especially at flat
viewing angles. On the other hand mipmaps use round about one third more
memory than "normal" textures.
Mipmaplevels:
| NO MIPMAP | No mipmaps are used |
| N_MIPMAP_N | Unfiltered mipmaps without interpolation between mipmap levels |
| N_MIPMAP_L | Unfiltered mipmaps with linear interpolation between levels |
| L_MIPMAP_N | Mipmaps are linearly filtered without interpolation between levels |
| L_MIPMAP_L | Mipmaps are linearly filtered with interpolation between levels |
Frage 1:
Eine SW Textur mit der Größe 64x64 verbrauche 4096 Byte. Wie viel Speicherplatz wird insgesamt benötigt, wenn von dieser Textur Mipmaps erstellt werden?
| Level 0 | $ 64 * 64 = 4096\ Byte $ |
| Level 1 | $ 32 * 32 = 1024\ Byte $ |
| Level 2 | $ 16 * 16 = 256\ Byte $ |
| Level 3 | $ 8 * 8 = 64\ Byte $ |
| Level 4 | $ 4 * 4 = 16\ Byte $ |
| Level 5 | $ 2 * 2 = 4\ Byte $ |
| Level 6 | $ 1 * 1 = 1\ Byte $ |
| Gesamt: | $ 5461\ Byte $ |
